INTERMITTENT FEELER Application filed 'July 13,,

This invention relates to a feeler for looms, which is tripped intermittently long as there is a considerable working supply of filling on the bobbin, but remains in feeling position when the filling on the bobbin ap proaches exhaustion, so as to feel the condition of the filling at each detecting beat.

The object, of the present invention is to provlde a feeler which has all the advantages of the intermittent operation above mentioned, and which is at the same time simple and inexpensive in construction, and easily, adapted to any loom now muse.

The specific construction and, operation of my improved feeler. mechanism, andithe The invention is illustrated in connection with a. feeler '5, whichis supported in the usual relation to the bobbin 6 by' a slide 7, which is mounted in a casting 8 connected with the loom side 9. A coiled spring 10 is mounted on the slide 7 between the front .end of the casting 8 and a shoulder 11 formed on the slide '4',

and urges the latter, and the feeler 5 carried thereby, toward the bobbin. The slide 7, however, is normally held in its forward position by a latch 12,

which engages a shoulder 13 formed on the slide; I v I The latch 12 is mounted on a pivot bolt 14;, which is supported'in a pair of ears 15 secured to the casting 8. A contractile coiled spring 16 is attached at one end to a pin 17 secured in the latch, and is attached at its other end to a hook 18 secured to the side of the casting 8, so that the spring 16 normally acts to hold the latch 12 behind the shoulder 13. 1

The latch 12 is formed with a slotted ear 19, extending outwardly from the pivot bolt 14, and a vertical bar cooperates with the slotted car 19 to retract the latch 12, and trip the feeler under certain conditions. The

upper endof the bar- 20 passes through the ear 19, and is formed witha longitudinal slot 21, in .whichastud bolt 22 is adjustably secured. The lower portion of the vertical bar 20 is guided in a bracket 23 securedto the loom side 9; A contractile coiled "spring 241s attached at one end in a hole 25-. formed a in thebar 20, and is connected at its other end to a flange 26, extending laterallyfro-in the bracket The lowerend of thef bar 2O is. adapted to-ride' on the rim of a Wheel 27 secured to the take-up shaft 28. The stud bolt 22 is so adjusted thatas long as the lower end of the bar 20 rides on thefrim of the wheel2i', the latch will rem-ainin-engagement with the shoulder 13 of. the ;Slld;E .7..

The wheel 27, however, is formed with a number ofnotches 29 in its periphery,and

when the lower end ,of the bar 20 drops into one ofthese notches, the bolt-22strikes the ear 19 and actuates the latch 12 to trip the i feeler.

The wheel 27 is shown in the drawing as having three notches 29, so that if the wheel makes one revolution for every seventy-eight picks,

every twenty-six picks. As longas vthere'is the feeler will be tripped once "for :a considerable working supply of filling on i the bobbin, the slide? will be returned at the next detecting beat; and will remain latched until the lower end of-the bar20.

reaches the next notch 29. If, -however,'the filling on the bobbin is approaching exhaustion, it will not be sufficient to return the slide 7 far enough for the latch to engage the shoulder 13 again, sothat the feeler willremain in feeling position, and will feel the condition of the filling at each detecting beat until the bobbin is changed, whereupon the intermittent action of the filler is resumed.

By the use of the mechanism above described, the feeler normally acts only once for every twenty-six picks, thereby avoiding the cutting of the filling, which would result if the feeler acted atevery' pica. By means of'the construction above described,

this intermittent feelerractio n maybe attained at a very moderate expense. .Its action is simple and positive, and it maybe easily adapted to any type of loom now in use. I

While I have shown and described in detail the construction of one form in Which the invention'may be embodied, it is apparent that many of the details thereof may be modified to a considerable extent without I l tany material departure-from the salient "features ofther invention as set forth in the claims.
